We did stay in Jeff apartment for almost a week and had a great time, family of 4+1 friend.
The apartment is small but very clean with 2 good size bedrooms , bathroom with good size shower and everything was inside from microwave oven to washing machine at a small balcony.
This is a very nice house with swimming pool and a gym at the 5 floor and everything is clean and well maitained.
Great location near skytrain so very easy to go everywhere in Bangkok and big Tesco-Lotus shop on the other side and 7-11 shop on the first floor.
Jeff is a great host and was in good contact with us through e-mail.
We will be back next year to Jeff apartment.
